AstraZeneca is the third pharmaceutical company in recent weeks to say it has a potentially viable coronavirus vaccine, and a cheaper one at that. With Marketplace’s Marielle Segarra, we’ll talk about how businesses can influence public health once we have a vaccine and even dare to imagine a day when kids can permanently go back to school. Plus: We talk about the people President-elect Joe Biden has tapped to run the Treasury and State departments. Did you know Antony Blinken has a singing career?

Here’s everything we talked about today:

• “3rd major COVID-19 vaccine shown to be effective and cheaper” from the Associated Press

• “Vaccination will be required to fly, says Qantas chief” from the BBC

• “Biden Picks Janet Yellen for Treasury Secretary” from The Wall Street Journal

• “‘The end is in sight’: Experts express optimism about COVID-19 pandemic coming to a close” from the Boston Globe

• “Key government agency acknowledges Biden’s win and begins formal transition” from CNN

• Antony Blinken’s Spotify page

• And this Janet Yellen meme
